Math question: If 1420 is multiplied by the sum of its digits added to the product of its digits, what is the result?

To find the result, we start by breaking down the number 1420. The sum of its digits is 1 + 4 + 2 + 0 = 7, and the product of its digits is 1 × 4 × 2 × 0 = 0. Now, we multiply 1420 by (7 + 0) = 7. Therefore, the result is 1420 × 7 = 9940.

Math question: If 1420 is divided by the sum of its digits, what is the quotient?

To solve this, we need to find the sum of the digits in 1420, which is 1 + 4 + 2 + 0 = 7. Now, we divide 1420 by 7. The quotient is 1420 ÷ 7 = 202.85714285714285714, which can be approximated to 202.86. Thus, the answer is 202.86, representing the quotient when 1420 is divided by the sum of its digits.

Math question: What is the smallest perfect square that is divisible by 1420?

To find the smallest perfect square divisible by 1420, we need to prime factorize 1420 as 2 * 2 * 5 * 71. We observe that for a perfect square, each unique prime factor must have an even exponent. Since 71 is present, it must have an exponent of at least 2. To have the smallest square, we assign the lowest even exponent possible, resulting in 2^2 * 5^2 * 71^2 = 142,020,100 as the smallest perfect square divisible by 1420.
